A 63-year-old man was transferred to our hospital for hematochezia syncope. First colonoscopy revealed colonic diverticulosis in the cecum and ascending colon, but the precise bleeding point diverticula was not determined. After the colon has bees purged with polyethylene glycol, the second colonoscopy was able to identify an exposed vessel with the diverticulum in the ascending colon. The diverticulum was closed by 3 pieces of clipping devices. The patient has not been re-bled. Since the wall of colon diverticulums is very thin, the clipping is better than ehanol-injection or heater-probe. To identify the precise point of bleeding make us do easy colonoscopic hemostasis. In this case, it is very important to purge the colon as much as possible to identify the precise bleeding point of the colon bleeding.
